Ameriglo Pro-Glo Tritium Square Front Sight .165X.140 Org For Glock~

The AmeriGlo Pro-Glo Tritium Square Front Sight is a self-illuminating night sight built for Glock pistol owners who need reliable aiming solutions in low-light and no-light conditions. Unlike conventional sights that fade when the sun goes down, this tritium front sight glows for nearly two decades without batteries or charging, making it equally effective whether you're at the range at dusk, hunting predators, or managing home defense in darkness. The square blade profile and bright green tritium lamp create a distinctive, fast-acquiring sight picture that works around the clock.

AmeriGlo engineered the Pro-Glo specifically for shooters who demand consistency across conditions. The tritium illumination is paired with a luminescent orange ring around the sight blade—this dual-light system means you get glowing tritium at night and a high-contrast sight picture in daylight, covering every lighting scenario. The 0.165-inch height is dimensioned to pair with standard Glock slide cuts, and the steel construction stands up to the recoil and daily carry wear.

Whether you run a Glock for home defense, competition, or duty, this front sight removes the guesswork from target acquisition when ambient light disappears. The green tritium is unmistakably visible in darkness, and the square geometry makes the sight naturally fast to align. Installation is straightforward on any Glock model, and once in place, you've got two decades of maintenance-free illumination.

Frequently Asked Questions

Will this front sight work on my Glock?

Yes. The Pro-Glo tritium front sight is designed to fit all Glock pistol models that use standard dovetail slide cuts. That covers the full Glock lineup from subcompact to full-size frames.

How long does the tritium glow last?

The tritium lamp is illuminated for approximately 20 years of continuous use. After that period, the glow will fade; however, the sight remains functional as a conventional steel sight and can be replaced if needed.

Is this a front sight only, or does it come with a rear sight?

This is a front sight only. You will need to source or retain a compatible rear sight separately to complete your sighting system.

What's the difference between the tritium and the orange ring?

The green tritium glows in darkness and low-light conditions without any external power. The luminescent orange ring surrounds the tritium vial and provides a bright, high-contrast aiming point in daylight and bright conditions. Together, they give you reliable sighting in any light.
